Campagnolo Chorus Ultra-Torque Carbon Crankset

Campagnolo is all about drivetrain evolution and their Chorus Ultra-Torque Crankset proves it. The carbon cranks and 4-arm spider feature a unified bolt pattern that allows for all three chainring standards. This design incorporates an 8-bolt pattern with a spider arm that not only holds the chainring in place by way of the bolt, but also supports the chainring to increase system rigidity. The integrated Ultra-Torque spindle joins the crankset together via a toothed Hirth joint in the center.
